The clinical diagnosis of the presence and severity of tricuspid insufficiency is difficult and is complicated by the transient nature of this abnormality as well as its usual occurrence in subjects with other valve disease. This paper presents correlative hemodynamic data from 100 consecutive catheterized patients with valvular heart disease in 90 of whom the presence of tricuspid insufficienc...
etralogy of Fallot with or without pulmonary atresia ccounts for approximately 10% of all forms of congenital eart disease. Establishing unobstructed blood flow between he right ventricle (RV) and the confluence of the pulmoary arteries using the transannular patch technique or via he insertion of an interposition graft valve between the RV nd pulmonary artery have been the main surgical option...
Valvular involvement by disease causes stenosis, insufficiency (regurgitation or incompetence), or both. Stenosis is the failure of a valve to open completely, thereby impeding forward flow. Insufficiency, in contrast, results from failure of a valve to close completely, thereby allowing reversed flow. These abnormalities can be either pure, when only stenosis or regurgitation is present, or mi...
The valvular disease usually involves two conditions: valvular stenosis and valvular insufficiency. Valvular stenosis occurs when a valve opening is smaller than normal due to stiff or fused leaflets. The narrowed opening may make the heart work very hard to pump blood through it. This can lead to heart failure. All four valves can be stenotic (hardened, restricting blood flow); the conditions ...
BACKGROUND We present the case of a 69-year-old female patient with giant aortic aneurysm who underwent previously multiple cardiac surgeries or interventions. CASE REPORT Ross procedure was performed in 2006 due to aortic valve regurgitation and aneurysm of the ascending aorta. In 2010 the patient was re-admitted for pulmonary valve insufficiency and a transcatheter pulmonary valve was implant...
Twenty nine patients (19 male, mean (SD) age 6.25 (0.5) years (range 0.16-15 years] with typical pulmonary valve stenosis were treated by balloon dilatation of the pulmonary valve. They were studied by echocardiography before the procedure, immediately after it, and at follow up (mean (SD) 10.2 (5.6) months, n = 18). The morphology of the pulmonary valve, the right ventricular-pulmonary artery ...
background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...
background: percutaneous balloon mitral valvotomy (bmv) is the gold standard treatment for rheumatic mitral stenosis (ms) in that it causes significant changes in mitral valve area (mva) and improves leaflet mobility. development of or increase in mitral regurgitation (mr) is common after bmv. this study evaluated mr severity and its changes after bmv in iranian patients. methods: w e prospecti...
We present the case of a 72-year-old woman diagnosed with rheumatic fever at the age of 6. In 1972, she was diagnosed with mitral valve insufficiency and mitral valve stenosis, then in 1974, a decision was made to perform mitral valve replacement surgery with a 32-mm Braunwald-Cutter ball cage prosthesis. An echocardiogram performed in 2014 revealed normal biventricular systolic function, mecha...
OBJECTIVE This study aims to analyse long-term results after correction of truncus arteriosus in all patients operated in one institution over 28 years. METHODS Between 1981 and 2009, 83 patients, median age 54 days, underwent repair of truncus arteriosus. Interrupted aortic arch was present in 14 (17%), severe truncal valve insufficiency in 10 (12%) and non-confluent pulmonary arteries in fi...
